OIL BURNING HEATER Filed Aug. 22. 1952 2 Sheets-Sheet 2 INVENTOR. d i9 Enammmu HTUQMEQ United States Patent OIL BURNING HEATER Benjamin H. Turner, Corryton, Tenn. Application August 22, 1952, Serial No. 305,741 1 Claim. (Cl. 126-110) This invention relates to space heaters, and more particularly to an improved space heater of the liquid fuel type.

A main object of the invention is to provide a novel and improved space heater which is simple in construction, which is safe to use, and which is eflicient in operation.

A further object of the invention is to provide an improved oil burning space heater which is inexpensive to manufacture, which is sturdy in construction, and which is economical in fuel consumption.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure 1 is a side elevational view of an improved space heater constructed in accordance with the present invention.

Figure 2 is a horizontal cross sectional view taken on the line 2-2 of Figure l.

Figure 3 is a vertical cross sectional view taken on the line 33 of Figure 1.

Figure 4 is a horizontal cross sectional view taken on the line 4-4 of Figure 1 in the direction of the arrows indicated in Figure 1.

Referring to the drawings, the improved space heater is designated generally at 11 and comprises a vertically disposed tubular casing 12 having the generally Z-shaped supporting legs 13 secured to the bottom rim thereof, as illustrated in Figures 1 and 2, to support the casing 12 in a stable position. Designated at 14 is a relatively obtuse conical baffle plate which is secured at its periphery to the intermediate portions of the respective supporting legs 13, whereby said baflie plate is secured in horizontal position with its apex directed upwardly as is clearly shown in Figure 3. The casing 12 has the annular bottom wall 15 and the annular top wall 16. Integrally formed with the top wall 16 and depending axially through the tubular casing 12 is the downwardly tapering vertical air conduit 17 which is secured at its bottom rim to the upturned annular inner rim 18 of the bottom wall 15. From Figure 3 it will be seen that an annular air discharge passage is defined between the baffle plate 14 and the bottom wall 15 of the tubular casing 12.

Secured to the upper portion of the tubular casing 12 is a supporting bracket 19 on which is mounted an electrically driven air blower 20 having an outlet conduit 21 on which is rotatably secured the air discharge tube 22, said discharge tube being provided with an elbow-shaped discharge nozzle 23. As shown in Figure 3, the discharge tube 22 may be positioned so that the discharge nozzle 23 points downwardly through the downwardly tapering con maximum discharge of air through said conduit, or alternatively may be rotated to any selected angular position providing a reduced rate of air flow through the conduit 17. The air blower 20 is provided a with the screened inlet port, shown at 24, whereby air may be drawn into the blower from the atmosphere.

Mounted on the bottom wall 15 of the tubular casing 12 concentrically with the conduit 17 is the apertured annular shell 25 which is provided with the inturned, serrated top rim 26. Secured on the annular bottom wall 15 of the casing 12 in the lower portion of the shell shell 25 through the apertures thereof to combine with the vaporized fuel and to promote the combustion of the fuel.

valve means, shown at 31 for regulating the draft through the flue. The upper space in the tubular casing 12 to which the flue 30 is connected is designated at 32. The upper space 32 is defined by a horizontal annular partition wall 33 which is secured in the casing 12 around the vertical air conduit 17, as shown in Figure 3, the partition plate 33 being formed with a relatively large notch 34 to allow the products of combustion to pass upwardly into the space 32 and thus escape from the burner through the line 30.

In operation of the device,

plate 14 and bottom Wall through the heater, the air 13 heated by the gaseous prodproducts of combustion are distributed and diffused along the external surface of the conduit 17 by the serrations of rim 26.

Fuel is admitted to the burner trough 27 from a fuel supply conduit 35 through a manually controlled valve 36 which may be adjusted to regulate the supply of fuel to the burner trough.

When it is desired to adapt the burner for the use of gas as a fuel instead of a liquid fuel, the annular trough it is intended that no lnmtations be placed on the invention except as defined by the scope of the appended claim.
